Claims.

This invention relates to the manufacture of shoes the uppers of whichcomprise spaced portions the ends of which are overlasted upon andattached to a face of the insole and is herein 5 illustrated in itsapplication to the manufacture of a strap sandal.

In the lasting of strap sandals two procedures have commonly beenemployed. According to one procedure the ends of the straps are pulledover upon and fastened in place by tacks, after which the ends of someor all of the straps are stapled to the insole. According to the otherprocedure, in which no tacks are used, the end of each strap, as soon asit has been pulled over upon the bottom of the insole, is held in placeby the operators fingers and stapled to the insole.

The present invention provides a method by which the lasting operationmay be simplified and speeded up. To this end the insole is provided onno its sole-attaching face with a predetermined pattern of spacedcoatings of cement which occupy the positions at which the ends of thestraps are to be attached and which are co-extensive at least with saidends. These coatings are preferably applied simultaneously by a machinehaving a cement-applying die of the desired pattern; and the cement ispreferably a colored cement which will contrast strongly with the colorof the insole so as to indicate at a glance exactly where the ends ofthe straps should be placed. With the insole prepared in this manner andthe ends of the straps coated with cement, the straps may be quicklytensioned about the last and their cemented ends pressed down upon thecoatings to 5 hold them temporarily in place after which the permanentfastening, for example by staples, may

be carried out.

Referring now to the accompanying drawings:

In the manufacture of the strap sandal herein illustrated there isapplied to the forepart of the sole-attaching face of an insole II apredetermined pattern of spaced coatings of cement 13, the pattern beingsuch that the coatings occupy the positions at which the ends of thecross straps 15 of the forepart of the upper are to be attached. Thespaced coatings l3 may be applied in any desired manner, for example bymeans of the cement applying machine disclosed in application Serial No.153,611, filed July 14, 1937 in the name of Herbert E. Edwards. Thismachine, a portion of which is shown in Fig. 1, comprises a bed or tableI! upon which an insole is placed, a die holder l9, and a removable andreplaceable die 2| having cement-applying members so located that whenthe die is brought down upon the insole by swinging the handle into theposition shown, there is applied to the forepart of the insole thepattern of spaced coatings I3 shown in Fig. 2. The coatings 13 arepreferably stripes of cement colored to contrast strongly with the colorof the insole, extending from the edge of the forepart of'the insoleobliquely toward the rear, and of a width at least equal to that of thestraps. The ends of the straps I5 which are to be lasted over upon andattached to the face of the insole are coated with cement, as shown inFig. 3, for example by means of a brush 25. The insole II is tacked tothe bottom of the last and the straps are tensioned one at a time andtheir cement-coated ends drawn over and pressed down upon the cementcoatings IS on the insole, for example by means of the operatorsfingers, the pressing down of a strap being shown in Fig. 5.

After the straps have thus been fastened temporarily in place, they arepermanently fastened by metallic fasteners such for example as staples.To this end a staple fastening machine such for example as thatdisclosed in United States Letters Patent No. 2,057,072, granted October13, 1936, upon an application filed in the name of Dennis J. Sullivan,may be used, a portion of such a machine being shown in Fig. 6. Asshown, a staple 21 is driven through each strap and through the insole,the points of the staples being clenched by means of a thin narrow anvil29 which is adjustably fastened to the frame of the machine and may bereadily caused to enter between the insole and the bottom of the last.

After the straps have been fastened to the insole, the ends of thestraps are trimmed and a filler piece 3| cemented in place. Thereafteran outsole 33 may be attached in any desired manner. As herein shown,the outsole is attached by cement, the margin of the outsole and theexposed sides of the overlasted ends of the straps l5 having beenpreviously roughed, as is customary, to facilitate the securing of asatisfactory bond between the outsole and the straps.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. The method of making a shoe the upper of which comprises spacedportions which are attached to the sole-attaching face of the insole,said method comprising providing upon said face, prior to the lastingoperation, a predetermined pattern of spaced coatings of cement, saidcoatings occupying the positions at which the ends of the spacedportions of the upper are to be attached, coating said ends of saidportions with cement, overlasting them, pressing them down upon thecoatings, and completing the manufacture of the shoe including attachingthe outsole.

2. The method of making a shoe the upper of which comprises spacedportions which are attached to the sole-attaching face of the insole,said method comprising providing upon said face, prior to the lastingoperation, a predetermined pattern of spaced coatings of cement coloredto contrast with the color of the insole and occupying the positions atwhich the ends of the spaced portions of the upper are to be attached,coating said ends of said portions with cement, overlasting them,pressing them down upon the coatings, and completing the manufacture ofthe shoe including attaching the outsole.

3. The method of making an insole for a shoe the upper of whichcomprises spaced portions which are to be attached to a face of theinsole, said method comprising applying simultaneously a plurality ofspaced coatings of cement to said face in the localities at which theends of the spaced portions are to be attached.

4. The method of making an insole for a shoe the upper of whichcomprises spaced portions which are to be attached to a face of theinsole, said method comprising applying, prior to the lasting operation,a plurality of spaced coatings of cement to said face in the localitiesat which the ends of the spaced portions are to be attached.
